What is effective atomic number? Calculate effective atomic number of copper ( Z = 29 ) in (Cu ( NH3)4)2+
एका वाक्यात उत्तर
उत्तर
Effective atomic number (EAN) in a complex is defined as the total number of electrons present around the central metal ion.
EAN = Atomic number (Z) – Oxidation number + 2 × Coardination number
Let us consider a chemical complex [Cu(NH3)4]2+
The atomic number of the central metal atom (Cu) Z = 29
Oxidation number = +2
Coordination number = 4
EAN = 29 – 2 + (2 × 4)
EAN = 29 – 2 + 8
EAN = 35
